AndroidManifest.xml Error: Attribute 'allowBackup' Conflict Solution

Solution:

To fix this error, you need to add the 'tools:replace' attribute to the '' element in your AndroidManifest.xml file.

1. Open your AndroidManifest.xml file.
2. Locate the '' element.
3. Add the following attribute to the '' element: tools:replace='android:allowBackup'
4. Your '' element should now look like this:

<application android:allowBackup='true' tools:replace='android:allowBackup' ...>

5. Save your changes and rebuild your project.

By adding the 'tools:replace' attribute, you are telling the build tools to override the conflicting attribute from the geopackage-android library with the value from your own AndroidManifest.xml file.
